METALLIC JAR-COVER.

Specification of Letters Patent.

Patented July 23, 1907.

Application filed August 13,1906. $erial No. 330,286.

To all whom it may concern:

Be it known that I, JULIAN P. LYoN, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Metallic Jar-Covers; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to metallic bottle caps; it has for its object an improved cap easily, quickly and economically constructed from sheet metal.

The cap in which the invention is embodied consists essentially of two pieces, one a disk-like piece that covers the opening of the bottle, and the other a split ring made from a strip of sheet metal that holds the disk in place and is itself held from expanding or spreading by a locking engagement that is employed to hold the disk and the bottle together.

In the drawings:-Figure 1, shows the split ring in perspective. Fig. 2, shows a washer or cork employed underneath the disk. Fig. 3, is a form of disk nearly tubular in construction, but provided with a slightly upturned edge used for locking purposes and hangers used to aid in holding the disk in place. Fig. 4, is a disk without hangers, but with an upturned locking rim. Fig. 5, is a disk without an upturned locking rim and with hangers. Fig. 6, is a section showing the locking engagement of the disk shown in Fig. 3. Fig. 7, is a sectional view showing the locking engagement of the disk shown in Fig. 4. Fig. 8, is a section showing the locking engagement of the disk shown in Fig. 5. Fig. 9, shows the band used with a washer or gasket alone.

The hangers of the cover shown in Fig. 3, serve to hold the cover in place and can be much more economically made, using less material than a full hanging flange.

The locking ring of Fig. 1, is made from a strip of metal 2, having an inturned rim 1, on that edge which lies at the top in the assembled structure. Preferably the ring is grooved with a strengthening groove 3, or if greater stiffness of ring is required, several corrugations may be used, below which is a hanging edge adapted to be turned under the collar 4, at the end of the neck of a bottle, or into a groove at any convenient point below the top of the jar. This ring is used with each of the several cover plates shown in the drawings.

5 indicates a disk of metal provided with an upturned flange 6 and with hanging lugs 7 adapted to engage outside the collar of the bottle with which the cover is employed and to prevent the disk from slipping out of place on the washer prior to the time the ring is used to secure it permanently in place, also to hold the disk in place as a jar cover after the band is removed. These lugs, (being cut from waste corners of metal necessary to form the disk) makes cost of the disk less'than where a depending flange is used and answers the same purpose. v

8 indicates a washer or gasket of any suitable material, preferably a thin slice of cork.

9 indicates a disk withan upturned and somewhat corrugated rim 10 adapted to engage under the inturned flange 1.

11 indicates a plain disk with downturned lugs 12, which may be used in place of either the disks 5 or 9. The disk 11 does not, however, so securely interlock with the rim as either forms 5 or 9. v

In assembling the cover, the packing gasket 8 is placed over the top of the bottle, the disk placed thereover. The ring is next slipped over the bottle mouth with the inturned flange 1, engaging over the upturned edges of the disk 5 or the disk 9, the closure is then subjected to downward pressure and the hanging flange is then bent inward under the collar of the bottle mouth to secure the ring in place, or preferably, the gasket or asher with disk and band may be furnished the use i all together, and ready to place on the bottles.

When either the forms 5or 9 are used the upturned rim of the disk engages under the curved inturned flange 1, and interlocks with the same to prevent the ring from spreading. In neither case is it necessary to lap the ring or secure together the ends of the ring' at the meeting edges 13 and 14. If the disk 11 is used, the rigidity of the material of the ring strengthened as it is by the inturned flange and by the groove 3, or grooves if needed, and. further strengthened as it is by the inturned lower flange 15, prevents the ring from spreading. A groove may be made in the cover or the edge of the bead may be sunk into a cover of soft material; Fig. 9 illustrates both ideas.

In all the forms shown, the split ring is formed from a single straight strip of material with a bead turned on its upper edge to hang inward toward the center of the strip when it is bent to ring form, and there is preferably the groove 3, which serves to hold the cap and washer from escaping from the assembled structure when the parts are assembled preliminary to placing them over the jar in the way in which they may be assembled for commerce. The groove 3 also serves as a fulcrum to bear against the collar at the time the, capping machine is used to inturn the flange- 15 at the lower edge of the web. The inturned head engages over and holds between itself and the web some part of the cap, or cap and washer, whether the cap be provided with a beaded corrugation as 1Q, with an upturned flange as 8, or simply sunk into a groove 16 in the material. I v

What I claim is:-

1. In combination with a jar provided with a collar about its upper end, a disk provided with an upturned 2. In combination with a jar provided with a collar about its \upper end a plate adapted to cover the jar and provided with jar engaging parts around its outer edge, a split ring provided with a bead adapted to overhangvthe jar cover and engage therewith, and also provided with a horizontally grooved, Web, 'the lower part of which is adapted to be turned in under the collar of the jar, the parts being adapted to interlock to prevent the removal of the assembled parts, substantially as described.

3.- In combination with a bottle provided with a flanging collar around its top, a disk provided with an upturned flange adapted to seat thereon, said disk having a plurality of depending portions adapted to laterally engage the outer periphery of said collar, and a split ring adapted to engage about said collar and disk, being provided with a bead around its upper edge adapted to engage the upturned flange of the disk and having its lower portion horizontally grooved to facilitate the bending thereof under said collar, substantially as described.

' 4. In combination with a jar whose 'upper end is surrounded by an integral collar, a resilient plate adapted to rest thereon, a split ring engaging about said plate and collar provided with a bead along its upper edge adapted to' interlock with the'edge of said plate, its lower edge being adapted to be bent under said collar to hold it and said plate rigidly in position with respect to the top of the jar, substantially as described.

5. In combination with a jar having a projecting collar about its top, a disk adapted to seat thereon a split ring provided with abead adapted to engage over the edge of said disk and hold the same closely against the jar top, its lower edge being adapted to be bent under said collar, substantially as described.

6. In combination with a jar provided with anencircling collar at its top, a disk provided with depending projections adapted to engage thereabout, a split ring having an inwardly projecting bead along its upper edge, adapted to engage over the edge of said disk and to hold the same closely against said top, its lower edge engaging under the collar, substantially as described.

In testimony whereof, I, sign this specification in the presence of two witnesses.
